The Antikythera Mechanism is an ancient Greek analog computer that was discovered in the early 1900s on the Antikythera shipwreck. This device has been described as the world’s first known astronomical calculator and has been hailed as one of the greatest technological achievements of ancient times.
The mechanism is believed to have been built around 150-100 BC and was designed to calculate the positions of the sun, moon, and planets in relation to the zodiac, as well as predict eclipses and the dates of the four-year athletic games in ancient Greece.
The Antikythera Mechanism was made up of at least 30 bronze gears, with some estimates suggesting that the total number of gears could have been as many as 72. The gears were housed in a wooden case that measured approximately 33 centimeters by 18 centimeters by 9 centimeters and was covered in inscriptions that provided information about the mechanism’s functions.
The mechanism was operated by turning a hand crank, which in turn rotated the gears and moved pointers that indicated the positions of the sun, moon, and planets on a series of dials. The mechanism was also equipped with a number of small pointers that could be set to specific dates, allowing the user to predict the positions of celestial bodies on those dates.
For many years, the Antikythera Mechanism remained a mystery, as no other device like it had ever been found. However, in the years since its discovery, archaeologists, historians, and scientists have worked to unravel the secrets of this remarkable machine.
One of the most impressive aspects of the Antikythera Mechanism is its accuracy. The device was able to predict the positions of the sun, moon, and planets with a high degree of precision, and could even account for some of the irregularities in their orbits. This level of accuracy was unheard of in ancient times, and it was not until the invention of the mechanical clock in the 14th century that similar levels of accuracy were achieved.
The Antikythera Mechanism also provides a fascinating glimpse into the technological and scientific achievements of ancient Greece. At a time when many people believed that the Earth was at the center of the universe, the mechanism demonstrated a sophisticated understanding of astronomy and the movements of celestial bodies.
